Anyone Tried Cake Balls In Brownie Molds?

I saw the new Wilton Brownie Molds in Michaels the other day and wondered how they would work for cake balls. I thought you could coat the mold with chocolate, add the cake, fill with more chocolate and then pop them out. Would that work? I have the hardest time making them look nice, even though I love the way they taste - I thought this would be an easy way to do it.

I've done that with certain candy molds, worked great! There was a tutorial on here back around Valentine's day where someone molded the cake ball mixture into the heart shaped silicone molds then dipped then and they looked awesome...
